The Microsoft Outlook outage that left thousands unable to use the email service is finally over.

It began as the work week started. Downdetector, which tracks outages and problems for online platforms,

showed a large spike

in reports of problems with Outlook starting around 8 a.m. PT on Monday, peaking at more than 6,000 reports at 8:17 a.m. By Tuesday morning, Downdetector showed fewer than 550 reports at 6 a.m. PT on Tuesday, but some people still faced problems.

Late Thursday, a Microsoft representative told CNET that “the issue has been resolved across all impacted services.” The company did not explain the cause of the problem.
